I suppose it depends what the goal is. If you want something which sounds exactly like the original audio, then just get a wav file and a couple of lines of code to play it.
Or if the aim is to do something not identical, but more versatile, you could get hold of a midi file for the tune and use either a multimedia library or custom-written code to play it. Or similar to the latter, make your own sound samples and program them to play in sequence ...
